Prepairing for Backtrack 5

Atm i dual boot Backtrack 4 R2 with Windows 7 x64. I have 2 partitions for windows and one for Backtrack.

And when Backtrack 5 comes i want to install it over the current "Backtrack 4 r2 partition". Is it just to install like i did for R2 or what should i do?

my mount:
